Change 4 1/5 to its improper form (large/5). Then put all of the numerators on the top, all of the denominators on the bottom:

large * 10 * 9

——————

5 * 21 * 20

Now, reduce according to common factors, such as the 10/20 portion. Keep doing that until there are no common factors between the top and the bottom. Do the remaining multiplication, and there’s your answer.
